BACKGROUND: Delmopinol is a third-generation anti-plaque agent used as a mouthwash to reduce plaque and alleviate gingivitis. OBJECTIVE: To create an overview of the anti-plaque efficacy of 0.2% delmopinol as an adjunct to normal oral hygiene measures by meta-analysis of completed clinical trials. MATERIALS AND METHODS: Eight double-blind, parallel-group studies were identified. Study durations ranged from 8 to 24 weeks. Five studies (n=913) involved supervised rinsing; three studies (n=467) involved unsupervised rinsing. These sets of trials were analysed separately and in combination. Efficacy outcomes comprised modified plaque index, modified gingival index (MGI) and gingival bleeding on probing (BOP). RESULTS: Delmopinol 0.2% was superior to placebo for the reduction of plaque scores in both sets of studies. Effects on MGI and BOP were also better with delmopinol 0.2% than with placebo. In most instances, 95% confidence intervals were wholly in favour of delmopinol. Pooled analysis of all eight studies confirmed statistically significant effects of delmopinol 0.2% compared with placebo (p<0.00001). Delmopinol met the efficacy criteria of the American Dental Association in studies of extended duration. CONCLUSION: Delmopinol 0.2% mouthwash is effective as an adjunct measure for reducing plaque burden and indices of gingivitis, whether or not it is used under supervision.

AIM: To review the literature on the effects of stannous fluoride on gingivitis. MATERIAL AND METHODS: The Medline and cochrane central register of controlled trials were searched up to August 2005 to identify appropriate studies. The primary outcome measure was gingivitis. RESULTS: Independent screening of titles and abstracts of 542 papers resulted in 36 publications (inter-reviewer ê score of 0.76), out of which 15 papers finally fulfilled the criteria of eligibility. For SnF(2)dentifrices, a statistically significant reduction in gingivitis was noted in comparison with control (weighted mean difference (WMD) of 0.15 (gingival index) and 0.21 (gingivitis severity index) (test for heterogeneity p<0.00001, I(2)=91.1% and p=0.03, I(2)=80.1%, respectively)). With regard to plaque reduction inconsistent results existed. On using the plaque index no differences were found, whereas meta-analysis of the Turesky index provided a WMD of 0.31 (p=0.01, test for heterogeneity p<0.0001, I(2)=91.7%). Because of insufficient data, a meta-analysis for SnF(2)mouth rinse and dentifrice/mouthrinse formulations was not performed. CONCLUSIONS: The use of SnF(2) dentifrices results in gingivitis and plaque reduction when compared with a conventional dentifrice. The precise magnitude of this effect was difficult to assess because of a high level of heterogeneity in study outcomes.
